261 Charge Density and 3D Toner Image in Magnetic Single-Component Development Process of Electrophotography

Abstract

For the purpose of analyzing the magnetic single-component development process of electrophotography, we measured 3D-figures and charge density of toner images on a photoreceptor drum and an OHP sheet with a co-focal laser focus displacement sensor and a Faraday cage. The results were as follows: (1) In a toner image on the photoreceptor, it was confirmed that mountain-like chain structures were formed parallel with development direction. (2) In a toner solid image, charge density in the center area is lager than that in the edge and volume density in the edge is lager than that in the center area.
